Patented Dec. 10, 1929 UNITED STATES PAT ENT OFFICE HENRI BOUTILLON, OF SURESNES, FRANCE DISTRIBUTING DEVICE FOR LIQUIDS In apparatus for the distribution of liquid in exactly measured quantities by means of .measuring reservoirs fed with the liquid to be distributed by a sucking reciprocating or rotary pump, it is necessary first to actuate the pump for approximately filling up the measuring reservoirs of the apparatus, then to operate the valves of these reservoirs for distributing the liquid they contain.

The working of the known apparatus is not therefore automatic, since it necessitates on the part of the person operating the apparatus successive operations which results in loss of time and may be the cause of errors in the distributiom v The present invention is adapted to remedy these inconveniences-and has for an object a distributing apparatus having ,a sucking pump raising the liquid into measuring reservoirs arranged at the upper part of the apparaitus which is essentially characterized by the fact that the rod of the piston of the sucking pump controls, through suitable members, a single valve so arranged as to regulate the admission and issue of the liquid in each of the measuring reservoirs.

According to the present invention, the rod of the piston of the pump is provided with a finger so arranged as to encounter, during the up and down strokes of the piston, the arms of a cross integral with the valve regulating the admission and issue of the liquid in each of the measuring reservoirs, this finger being pivoted in such a manner:

(a) As to move away when coming in contact with the cross and not to actuate the valve during the up stroke of piston (b) And then return to normal position for driving the said cross and actuating the valve during the down stroke of the piston and thus putting, in this new position of the valve, the filled up reservoir in communication with the outlet tube for the liquid and the empty reservoir in communication with the pump.

In order that the invention may be clearly understood, a. form of construction of the automatic distributor forming the subjectmatter of this invention will be described hereafter, by way of example only, with reference to the accompanying drawing in which:

As shown in the drawing, the automatic measuring apparatus in accordance with the invention comprises a base 1 provided, at its lower part, with atube 2 coupled to a central socket 3 of the said base and connected to a reservoir or other vessel containing the liquid to be distributed.

The upper part of the socket 3 carries a suction valve 4 and forms the bottom of the 9 barrel of the sucking pump 5 which is secured on the base 1 by means of tie rods 6 and is connected to a cap or head 7 carrying all the driving parts.

The piston 8 of this sucking pump is provided with a valve, not shown, and is secured to a rod 9 connected by a triangular arm 10 to a rack 11 suitably guided in a case or sheatlr of the cap or head 7. and in engagement with a pinion 12 actuated from the ex which retains the impurities of the liquid delivered and can be removed for cleaning purposes by taking off the plug 17.

The upper part of the apparatus is connected to the lower part by a second cap 22 having uprights 23 on which are hinged doors 24 forming with the uprights an enclosure for the driving mechanism when the apparatus is not in use.

On this cap 22 is secured a sheath or casing 25 connected to a flange 26 carrying the measuring reservoirs 27, said flange 26 being bored at its central part for receiving the shell 28 of a valve. The shell has, at its upper part, a port 29 with which is connected the filling tube 15 and, at its lower part, a second port 30 to which is connected the distributing tube 31.

This fixed shell has, moreover, two other ports 32 and 33 respectively communicating with channels34 and 35 provided in the flange 26 and opening in the measuring reservoirs.

In this fixed shell 28 is fitted a distributing valve 36 which is pressed in the said shell by a spring 37 bearing against the said valve and against a cap 38 closing the shell 28. The other end of the shell 28 is reduced at 28 and carries a stufiing box 39 through which the valve stem 36 extends.

According to the present invention, this valve 36 carries on its stem 36 a cross 40'and the triangular arm 10 connecting the rod 9 of the piston and its driving rack is provided with a verticalarm 41 having, at its upper end, a finger 42, provided with a roller 43, and

pivoted about an axis 44, the finger being held in a horizontal position by a spring 45. This pivoted finger 42, which thus follow the piston of the pump during its up and down strokes, is so arranged as to operate the cross 40, and the stein of the valve 36 only on the downward movement of the piston.

During the upward movement of the piston, thefinger 42 at the time it comes in contact with the arms of the cross 40, swings about its axis 44 so that it does not actuate, the valve 36 and that, if the latter occupies for instance the position illustrated in Fig. 13, the

liquid delivered by the pump flows, through the conduit 15, shell 28 and channel 34, into the left-hand measuring vessel.

When this vessel is filled up, the pump piston is brought back to its starting position illustrated in Fig. 3. During this downward movement, the pivoted finger 42,-held in a horizontal position by its spring 45, comes again in engagement with one of the arms of meats? l the cross and causes the latter to rotate trated in dotted lines inFig. 13,:so that the measuring vessel which has just been filied, empties, the liquid flowing out through the channel 34, ports 32 and 30 of the valve 36 and the distributing conduit.

The movement of the valve-36 by the downward movement of the piston to the position just described, to empty the left'hand measuring vessel, places the channel 35 leading from the right hand measuring vessel in communication with the filling tube-15 by means of the ports 29 and 33, so that upon the next upward movement of the piston the liquid raised thereby will pass into the right hand measuring vessel and fill the same. Upon the downward movement of the piston the valve 36 will other emptied by the downward movement of the piston.

The measuring vessels are .to be filled up to a predetermined level by the pump, and to prevent them from being filled beyond said level, an overflow pipe 49 is arranged in each vessel. The overflow pipes 49 are connected with a tube 49* connected with the container or reservoir, which contains the liquid to be distributed by'the apparatus.

In the form of construction illustrated, the measuring apparatus in accordance, with the invention isalso provided with a partial counter 50 which comes into action at each displacement of the rack by means of an abutment 51 on the latter, whilst the pinion l2 actuating the said rack 11 controls a counter 46 totalizing the quantities of liquid distributed.

These devices. are moreover indicatedonly of execution may of course be modified with-- out departing thereby from the principle of the invention.
